When discussing homosexuality, Christians like to point to Leviticus 18:22, which declares homosexuality an abomination. However, in Lev. 18:19, it says a man should not engage in sexual activity with a woman while she is menstrating. In Lev. 18:26, it says "But you shall keep my statutes and my ordinances and do none of these abominations".
Sounds to me like it is saying ALL of the acts previously described in the chapter are abominations, not just homosexuality. If this is the case, where are the Christians holding signs that say "God hates men who sleep with menstrating women"? I guess that just doesn't have the same ring to it. It would also mean adultery, incest, and beastiality are abominations as well.
If nothing else, Christians are consistent in their inconsistency.
